To @ZZ whom it' may concern.' Y Be .itlrncwn `that Yl, GORDON HOLLINGER, of Stjdacdba' in the county'of Waterloo,

` Province of Ontario, Canada, a subject of i devices.

the King of Great Britain, have invented certain new and Auseful Improvements in Thrashing-Machine Attachments, of. which the following is a specification.

This invention relates to thrashing machines provided `with pneumatic stacking It is desirable in such Ymachines to provide means for moistening the straw to allay the dust which ordinarily accompanies the discharge of the straw, but the straw re- .,quires to be evenly moistened without eX- cess in any one place otherwise heating and rotting is liable to occur when the straw is stacked. It is further important that Ano accumulation of water shall occur on any of the parts of the machine, as this would be liable to freeze `up when the machine was used under low temperature conditions as is frequently the case in Western Canada.

I am aware that it has been proposed to moisten the lstraw by sprinkling it on the straw decks, but this has never proved to be successful inpractice, and is subject to all the disadvantages hereinbefore referred to. My object therefore is to devise means for moistening thestraw which will not be subject to these defects, and whichV will enable any desired content to be added to the straw.

il attain my object byproviding the thresher with a water pipe extending through the end of the fan casing of the stacker vclose to the fan shaft, which'pipe extends a short distance within the casing and discharges, preferably, in a direction parallel to the fan shaft.

.The invention is hereinafter more fullyV described and illustrated in theaccompanying drawings, in which Fig. l is a side elevation of part of a thresher providedV with my improvements; andV Fig. 2 a cross section through part of the same. i

In the drawings like. numerals of reference indicate corresponding parts in the different figures.

1 is part of the frame of the thresher, and 2 one of the shafts of the same. This shaft may be any shaft which is constantly rotating with the thresher, when inoperation, and is used for the purpose which will hereinafter appear. In the present case, the

shaft chosen'is one of the shafts for operating 'the 'straw decks. A3 is the casing of the pneumatic stacker, which as is now usually the case., is built into the machine. This fan casing is provided with the usual discharge pipe 4. In the casing is located the fan 5, which is secured to the fan shaft 6, which is suitably journalled at the ends of the casing. 7 is a pump preferably of the centrifugal type. 8 is a suction pipe and 9 a discharge pipe. The suction pipe will be led to any suitable source of water supply while the discharge pipe 9 is led to one end of the fan casing and extended through the end close to the shaft 2, and, in such a manner, as to discharge axially of the fan casing. The pump 7 is provided with a suitable pulley connected by means of a belt 10, witha pulley secured to the end of the shaft 2. While the machine is running the pump is also running and a constant stream of water is forced into the fan casing, and is there, by the action of the fan, broken up into a fine spray and thoroughly and evenly mingled with the straw. The pump will be so proportioned and its speed adjusted, so as to supply just the amount of water, which is found desirable, though the supply may be regulated within certain limits by means of the valve 11 in the supply pipe. I find in practice that all the water is taken up by the straw and none left to accumulate on parts of the thresher. l find that any degree of moisture may be imparted to the straw even to the extent of causing heating and rotting, which is sometimes desirable when straw is Vto be used for fertilizing purposes.

What I claim as my invention is l. A thrashing machine provided with pneumatic straw stacking means including a fan, an imperforate fan casinggan inlet passage leading to the eye of the fan casing, and a discharge pipe, in combination with a water supply pipe extending through the end of the casing opposite the eye and adapted to discharge axially of the casing towards the inlet passage so that the water is discharged against the incoming straw; and means for regulating the flow of water.

2. A thrashing machine provided with pneumatic straw stacking means including a fan, an imperforate fan casing, an inlet passage leading to the eye of the fan casing, and a discharge pipe, in combination with a Water supply pipe extending through one end of the casing opposite the eye and adapted to discharge axially of the casing towards the inlet passage so that the Water is discharged against the incoming straw; means for regulating the iioW of Water; a piunp secured to the thresher having its dischargeV connected to said pipe; and means for drivvingsaid pump from one of the constantly l0 running shafts of the thresher.

3. A thrashing machine provided with pneumaticstratiT stacking means including a fanyan imperforate anrcasing, an inlet passage'leadingto the eyeof theVv-ancasngf and a discharge pipe in combination with a" Water supply pipeadapted to discharge Water into the straw in the opposite direction to the movement of the latter as it enters 'the fan casing andY before itpasses to the G'oi'epon HoLLrNeen.'v
